GPUs/NVIDIA GeForce RTX 3070 Ti/Wan Video 14B

Can NVIDIA GeForce RTX 3070 Ti run Wan Video 14B?

14B parameter Video Gen model on 8GB GDDR6X

Barely — requires CPU/RAM offloading
~1-3 tok/s (offload)
SpeedVery slow — expect 1-3 tokens/sec
QualityQuality is fine but the speed makes it impractical for interactive use

VRAM Requirements

Wan Video 14B is a 14B parameter model. At full precision (FP16), it requires 32GB of VRAM. Your NVIDIA GeForce RTX 3070 Ti only has 8GB — not enough even at maximum compression.

FP16 (Full Precision)32GB (need 24GB more)

Maximum quality, no quantization

Q8 (8-bit)18GB (need 10GB more)

Near-lossless, ~50% size reduction

Q4 (4-bit)11GB (need 3GB more)

Good quality, ~75% size reduction

Your GPU VRAM: 8GB GDDR6X at 608 GB/s bandwidth
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)
